Filed: 1989-08-03
Abstract: PURPOSE:To enhance the speed reducing efficiency and prevent the generation of backlash as in the case of gear transmission by adopting a planetary roller system which is a speed reducing mechanism performed only by rolling friction transmission combined with a differential mechanism. CONSTITUTION:An input shaft, that is, a center roller 5, is rotated by the driving of a motor provided outside, so that a driven roller 6 in contact with the center roller rolls, as well as a supporting member, by which the rotary pivot of the driven roller is fixed, is integrally rotated in the same direction concentrically with the center roller. In other words, the input rotating speed is largely reduced by a planetary roller mechanism that the driven roller is rotated around the center roller while being rotated on its axis, and transmitted onto the output shaft side. A flange member 13 is contact with the driven roller is rotated in the same direction following the rotation of the driven roller, and an output shaft formed coaxially with the flange member is rotated. In this case, the assembling of a pressure ring 18, the driven roller and the flange member forms a differential mechanism by double rolling friction.

Abstract: PURPOSE:To provide a superior image which is free from an image irregularity at the time of development by providing a doctor blade with an electret layer. CONSTITUTION:A developer 14 forms a magnetic brush 18 on a developing sleeve 16 and the brush is restrained by the doctor blade 20 and reacts on an electrostatic latent image in a photosensitive layer 24 at a nip position to form a visible image of the developer, which is transferred by a transfer mechanism 34 to transfer paper.

When magnetic developer particles 18 are charged electrostatically and negatively, the external surface of the electret layer is charged electrostatically and negatively. The developer after being agitated is held on the sleeve surface and when the developer passes between the blade and sleeve, i.e. a nap cutting gap, the blade limits the amount physically; and the developer receives electric resiliency from the electret having the same polarity with an electrostatic charging electrode and is applied with the magnetic attractive force of the sleeve in some case to cohere by compression, so the concentration of the developer is made uniform and the electrostatic charging performance is uniformed.
